2 Claims. (CI. 33-58) This invention relates to a rifle sight conversion attachment.

An object of the invention is the provision of a simple and efiicient device for converting the fixed, and semi-fixed, sights usually found on lower and medium priced 'rifles, to easily and quickly adjustable sights.

The National Rifle Association Instruction Manual for Junior Rifle Clubs states: Many inexpensive light rifles are equipped with crude, open sights. The only way to adjust such sights is by the trial and error method. Follow the general rule of moving the (rear) sight in the direction in which the shots should go. It is necessary to more or less guess at how much to move it up or down by means of the little step elevator or to move it from side to side by driving it through the slot in the barrel. Then shoot to see if it has been moved enough. If not, try again. It can easily be seen that such crude sight are unsatisfactory for eflicient target shooting, and should be replaced by more easily adjusted aperture or peep sights.

Therefore, another object of my invention is the production of a device which is easily and quickly attached to the sight already on the rifle, and permits quick and accurate adjustments for windage and elevation.

A still further object is the construction of a simple device which can be easily and inexpensively manufactured.

This is a divisional application growing out of my allowed application, Serial No. 676,706, filed June 14, 1946, now a Patent No. 2,473,891, granted June 21, 1949, Rifle Sight Conversion Attachment.

With the foregoing and other objects in view, my invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a fragmentary, perspective view of a rifle barrel showing the fixed or permanent sights thereon, with the sight device of this invention in position above one of said fixed sights.

Figure 2 is a view in side elevation of the front sight device.

Figure 3 is a top plan view of the front sight device.

Referring to the drawings, in which the preferred embodiment of this invention is illustrated, l designates an ordinary rifle barrel to which is fixedly secured a front sight 2 and a rear sight 3.

The front sight device of this invention comprises a flat oblong frame or body 4 which is provided with an oblong slot 5. The body 4 is also provided with a square slot 6 in which is slidably mounted the vertical sight post I. Sight post I is provided with scale 8. A set screw 9 extends into the end of body 4, the inner end of said screw being adapted to extend into slot 6, into engagement with sight post I for securing said post in an adjusted position. Two side set screw l0 are on the sides of the elongated body 4 contiguous to its outer end, while set screw I I is on the outer end of said body 4. When the body 4 is placed upon the fixed sight 2, said screws [0 and II are tightened to secure the front sight device upon the fixed sight 2. The set screw II will draw the rear of slot 5 against the opposite end of the sight 2; this screw I I will permit the device to fit sights of varying length.

The rear sight I2 is fully described in my allowed companion application, Serial No. 676,706, now a Patent No. 2,473,891, granted June 21, 1949, hereinbefore mentioned.

In operation the front sight post 1 is adjusted vertically to suit the condition, the scale 8 assisting in this adjustment. Therefore, with these attachments the operator can obtain perfect sights when using an ordinary rifle.

While I have. described the preferred embodiment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a device of the class described, the combination of a flat horizontal, oblong body provided with an oblong, horizontal slot, said body provided in its sides and one end with horizontal screws extending into said slot, said oblong body provided with a square slot between one end and said oblong slot, detachable sight means vertically slidable in said square slot, and a horizontal screw on the side of said body and engaging a side of said detachable sight means and holding said detachable sight means in an adjusted position.

2. In a device of the class described, the combination of a flat horizontal, oblong body provided with a longitudinally extending oblong slot, said oblong body provided between one end and said oblong slot with a vertical post-receiving slot,
